Eclipse
Aussie Chris:
Hi Shuggy.
I was wondering if I could ask a question that you might know the answer to, and hopefully it's not something that absolutely everyone knows and I'm the only daft fool in the world that doesn't...
What is a lunar eclipse, actually? I mean, as opposed to a new moon?
Ellemeno:
A lunar eclipse is when the earth gets in the way of the sun shining on the moon, and we actually see the shadow our planet casts on the moon.
A solar eclipse is when the moon gets between the sun and the earth, and we actually can see that the moon is in the way of seeing part of the sun.

Yes, it doesn't happen every month because the moon's orbit around the earth is tilted compared to the earth's orbit around the sun, but they line up every few years.

Yes, the moon's shadow falls on us. The area of full shadow is much smaller than with a lunar eclipse, because
* the moon is smaller than the earth, and
* the moon is much smaller than the sun, soa total solar eclipse is much rarer than a total lunar eclipse.
Also, everyone on the night side of the earth can see a lunar eclipse because it's on the moon. Only people in the full shadow of the moon on earth experience a total solar eclipse, but it's very impressive. The stars come out, animals go to sleep, and there are strange shadow patterns on the ground. When (or while) a solar eclipse is partial, there's a wonderful effect in dappled light, when every shadow forms tiny crescents.
Aussie Chris:
Um, so what is a new moon then? Isn't that also a shadow cast on the moon by the earth? Why don't we call that an eclipse too?

Boy, those are great pics Suggy! I tried to take some pictures too, but I broke my tripod last spring and I had to hold my camera in my hand when I took them. And I am very close to the city, and the lights from downtown were washing out the intensity of the moon.
What settings did you use? I used ss=4 sec., ap= F2, spot metering, noise reduction, 8x zoom (analog), OEV -2, ISO 1000.
Nice pics Suggy! :D
